Original application flledDecember 4, 1916, Serial No. 135,072. Divided and this application filed February 23, 1917. Serial No. 150,485.

To all whom it may concern:

Be it known that I, LOUIS H. "PERLMAN, a citizen of the, UnitedStates, residing at New York, in the'county of New York and State of New York, have invented certain new and useful Improvements in Demountable Rims and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in demountable rims for automobile -Wheels and more particularly to the type'known as transp-lit or cross-cut, that is, the type wherein an otherwise continuous tire carr ing ring is transversely cut for enabling t o ring to be relatively reduced in effective diameter for permitting the application and removal of tires having inextensible beads.

- Reference to my co-pending application, Serial No. 135,072, filed December .4, 1916, of which this is a division, is made for the purpose of identification.

The object in view is the formation integrally with the rim of means constructed in such manner as to facilitate the application and removal of a rim manipulating tool.

With this and more detail objects in view, as will in part hereinafter become apparent and in partbe stated, the invention comprises certain novel constructions, combinations and arrangements of parts as subsequently specified and claime I In the accompanying drawing Figure 1 is a perspective view of a rim embodying the features of the present invention.

.Fig, 2'is a transverse vertical section, of a tool receiving socket, taken on the plane indicated by line 22 of Fig. .3.

Fig. 3 is a plan view of the tool receiving socket, a fragment of the rim being shown.

Fig. 4 is a perspective view of a rim tool detached.

Fig. 5 is a transverse section taken on the plane indicated byline 5 '5 of Fig. 1, parts being seen in elevation.

Fig. 6 is a View similar to Fig. 2-, showing the socket in modified form.

This invention, while directed to improvemerits in d mountable .r m my be understood by a detail description of the operating tool whose use is facilitated by the improved rim. V H p Referring to the drawing bynumerals, 1 indicates an operating lever which is pivoted on a shaft 2 and has one of its ends ful crumed on pivot 3 carried by a bifurcated post 4. The free end of the postfl lis formed cylindrical ly and provided with diametrieally op osite outstanding locking pins 5. The shaft 2 is surrounded by sleeves 6, 6, arranged at opposite sides of the lever 1 and serving as spacers therefor. The shaft 2 is provided with a head at one end'and a nut oted onto the shaft in a position to swing freely thereon. The free end of each link is bent substantially at right angles and is preferably tapered to form a hook 8. Each book 8 is relatively straight, but as. will become apparent'serves the purpose of an ordinary hook. The links '7 are connected near their free ends by .a cross rod 9 having a head at one end engaging one of the links and a nut 10 threaded onto the opposite end portion and engaging the other. link. f An appropriate washer may be employed between'the nut and linkas also between the head of rod 9 and the adjacent link. 1

Rim 11 is provided with a tongue 12 outstanding from one end and formed with a book 13 adapted to enter a slotl lformed in the opposite end of rim 11 for receiving 1 said hook. The flanges of rim 11 at the.

slotted'end are formed with apertures 15 for receiving the hooks 8 of links 7. The op 0- site end portion of the rim 11 is provi ed with a radially-inwardly extending projection or stud 16 which is formed integrah with the rim. The stud 16 is formed with an axial recess overhung by a substantially annularfflange-H, the flange being inter-- rupted at diametrically opposite points by radial openings or slots 18. The slots 18 are disposed to be intersected by a line extending transversely ofthe rim and are of a size adapted to permit the passage of the pins 5, the recess in the stud 16v being pro.-

portioned to receive'the cylindrical lower end portion of the bare. Thus stud 16 formed into an undercut socket with lateral notches for access of the lateral projections to the undercut portion of the socket.

In operation, the rim 11 being in the noncollapsed condition seen in Fig. l, the cylindrical portion of bar 4 is introduced into the recess in stud 16 while the lever 1 is disposed to extend in a direction transversely of the rim. The pins 5 are passed through the slots 18 and then the lever 1 is swung to a position substantially alined with the rim, durin which movement the pins 5 are move beneath the overhanging flange 17. Thus the post 4 is quickly and efl'ectively anchored to the rim. The links then are caused to engage the opposite end portion of the rim; by .having the hooks 8 inserted in the apertures and the'nut 10 threaded up sufiiciently for tightening the links in the given position.

The stud 16, during operation of the rim on a wheel, is accommodated by a recess in the peripheral portion of the wheel body, not shown, and may serve as a driver for the rim.

It is especially desirable that the locking of the post 4 to the stud 16 shall be accomplished quickly and effectively so as to prevent loss of time and obviate possibility of. accidental disengagement. The cylindrical portion of the post 4 is proportioned to fit snugly in the socket or bore of the stud 16,

the

- so, that the post 4 may serve as a. fulcrum post and without liability of objectionable ooseness or play.

, The projecting tongue 12 may be formed 1 in any appropriate manner, the said tongue being produced in the structure shown in rawing by the provision of a separate socket, and a anchored to the web of the rim 11. Other shapes of tongues and other methods of connection therefor may be provided as may be desired.

It is to be noted that the rim 11 is provided with a valve stem hole, as at 19, surrounded by theusual drivin stud, the hole 19 being located in that en portion of the rim 11 which carries the socket provided by stud 16.

- What I claim is:-

1. A transplit demountable rim having an integrally formed tool receiving socket at one endportion, the other end portion bein adapted to receive part of an operating tool the socket'being formed to recelve a radially introduced fulcrum post and to hold said post rigidly in a radially extending position.

2. A transplit-demountable rimhaving a radially inwardly extending stud stamped from the material of the base of the rim and recessed to form an undercut socket having a notch opening into the undercut portion of the socket.

3. A transplit demountable rim having a radially inwardly extending stud recessed to form an undercut socket having a notch opening into the undercut portion'of the plate fixed to the outer face of the base of the rim and extending across the socket and provided with a recess in line with the main portion of the socket.

In testimony whereof I afiix my signature in presence of two witnesses.
